Lexan Fabrication


Other Available Facilities are…..


Conventional Drilling is available for high production batches making use of jigs and fixtures at low cost. The extensive range of industrial plastics available makes it necessary to have a team of very experienced machinist to produce and supply the correct customer specified size holes and cut outs. Furthermore at Sentinel we have experience in insulation materials. This includes Tufnol, Phenolic, Polyester and Epoxy materials. These react very different to Polypropylenes, Perspex, Makrolon®, Lexan®, and Nylons when routed, drilled, turned, milled and fabricated. With our range of CNC’s your requirements are better understood and guaranteed in our skilled hands. Plastic-machining-plastic-fabrication

Sub Assembly

GPO3 is well liked for being a material which can also be easily machined to bespoke applications. Thes Items are just some examples Insulating supports, high voltage insulation, and mounting panels. Hence Gp03 Materials are widely used to manufacture such parts.
